BAN D-CUTTER AND FEEDER.

SPECIFICATION forming part of Letters Patent No. 482,476, datedSeptember 13, 1892.

Application filed January 18, 1892. Serial No. 418,495. (No model.)

To all wwm t r11/ty concern.-

Be it known that I, DAVID GWIN, a citizen of the United States, residingat Edgerton, in the county of Platte and State of Missouri, haveinvented a new and useful Band-Cutter and Feeder, of which the followingis a specification.

This invention relates to band-cutters and feeders; and it has for itsobject to provide a feeding attachment for thrashing-machines which Willnot only cut the bundles of grain fed to the thrasher, but will also atthe same time shake and spread out the bundles of grain after being outand evenly feed and distribute the same to the thrasher-cylinder.

The invention also provides a feeding at- I tachment which shall be soconnected with the thrasher as to be easily thrown up and out of the waywhen not in use.

lVth these and many other objects in View, which will readily appear asthe nature of the invention is fully understood, the same consists inthe novel construction, combination, and arrangement of partshereinafter more fully described, illustrated,and claimed.

In the accompanying drawings, Figure l is a side elevation of aband-cutter and feeder constructed in accordance with myinventionapplied to the cylinder end of a thrashing-machine. Fig. 2 is a top planview of the same, showing the spreader-arms in dotted lines. Fig. 3 is avertical longitudinal sectional view of the same. Fig. l is a verticaltransverse section on the line 4L 4E of Fig. l.

Referring to the accompanying drawings, A represents the cylinder end ofa thrashingmachine, in which is located and revolved the toothedcylinder B, workin g over the ordinary concave, and in front of whichextends the opposite side arms C, inclosing the ordinary feeding-tableof the thrasher.

A feeder-frame D is hinged at d to the ends of the extended side arms Cand is supported upon the legs or supports d, connected with theopposite end of the feeder-frame and holding the samein position inalinewith the feeder end of the thrashing-machine, whereby the grain mayhe carried directly to the cylinder. In each end of the feeder-frame Dis j ournaled the endless belt or apron-shafts E, carrying thebelt-rollers c, over which passes the endless apron e', arranged to moveover and under the ordinary frame-floor c2, located between the endrollers c, and said apron is provided with the carrier-slats e3, securedthereto in the usual manner. The front apron-shaft E carries upon oneend thereof outside of the feeder-frame the speed-pulleys F, which areconnected by suitable belting with the other parts of the machine, asillustrated, all of which are driven from one of the thrashing-machinepulleys. The speed of the endless carrier may be controlled as desiredby changing the belt on said speed-pulleys and the adjacent pulleys, tobe noted. The feeder-frame D is provided upon each side, adjacent to thedelivering end thereof, with the opposite upwardlyextendingsupporting-arms G, which support and guide the opposite movableknife-cylinder bearingblocks II upon said feederframe. The said movableblocks H are provided upon their faces with the vertical grooves orslots h, which receive the upwardly extending arms G, which whileholding the said blocks in position allow the same to be free to move upand down without displacement, according to the size of the bundlespassing under the knife-cylinder- Each of said blocks II is furtherprovided with the top bearings 7L', which receive the knife-cylindershaft I, j ournaled therein and carrying the knife-cylinder J, Workingdirectly over the endless carrier adjacent to the delivering end of thefeederframe. Driving-pulleys fr' are keyed on one end of said shaft I,and by means of suitable belting passing over said pulley or pulleys, asillustrated, the said knife-cylinder is driven at the requisite rate ofspeed.

Rigidly secured upon the periphery of the knife-cylinder .I is a seriesof parallel rows of cutting-knives K. The said cutting-knives K areprovided with curved cutting-edges k, which extend rearwardly, or awayfrom the direction of rotation of the cylinder, and thus prevent thewrapping of the straw around the cylinder or drum and the choking of theina-- chine, as is common in other machines of this character.

Secured to the upper rear edges of the blocks H in rear of theknife-cylinder is the transverse fender-plate L, extending close to saidcylinder and provided with a series of notches Z, which allow the knivesK to pass through said plate as the knife-cylinder revolves and ICJserves to hold back any straw which may happen to cling to the knivesand causes it to drop onto the feeding-table of the thrasher.

J ournaled in bearings at the outer ends of the feeding-table are sidearms C, and directly under the delivering end of the feeder-frame is thetransverse multiple-crank shaft M, having a series of cranks m, whichreceive and carry the upper ends of the inclined notched feeder andspreader arms or bars N, which as the said crank-shaft is rotatedvibrate alternately with relation to each other, and thus effectuallyloosen up the bundle passing from the knifecylinder and evenly spreadthe grain, while at the same time delivering it to the cylinder D at thelower end of the same. Said feeder and spreader bars of course workdirectly over the feeding-table of the thrashing-machine, and in thepresent invention the lower ends of one or more are connected directlyto the lower end of the vibrating delivering-pan O. The saiddeliveringpan extends rearwardly the full length of said bars or armsand under the delivering end of the feeder-frame and serves to receivethe shattered grain and work it into the cylinder, as will be readilyapparent. A floatboard P is hinged upon the rod p, secured in the rearedge of the fender-plate L, and norlnally rests on the top of the grain,which leaves the knife-cylinder and falls upon the feeding and spreadingbars. The float-board P thus serves to hold the grain to its place andprevent the reciprocating and vibrating arms from throwing the grainabove the mouth of the thrasher.

It will be noted that the grain being fed upon the endless carrier atthe receiving end of the feeder-frame will be carried directly to therevolving knife-cylinder, which will cut the band and which will riseand adjust itself to accommodate the size of bundle and will deliver thecut bundle to the spreading and feeding bars beneath the hingedfloat-board in the manner just described and allow the same to be evenlyfed to the tlirasher-cylinder, the belts connecting the several pulleysof the machine of course being sufficiently loose to allow for a certaindegree of the vertical movement of the knife-cylinder. It may also benoted that by the connection of the feeder-frame with the separator thatthe same can be thrown up and out of the way when not in use, and thusprovide a convenient and efficient band-cutting and feeding attachmentwhich subserves all the functions herein set forth.

Y The construction, operation, and advantages of the herein-describedband-cutter and feeder are thought to be apparent without furtherdescription.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

l. In a band-cutter and feeder, the combination, with athrashing-machine having eX- tended side arms inclosing thefeeding-table in front of the cylinder, of an endless-carrierfeeder-frame hinged to the outer ends of said arms, a knife-cylinderjournaled upon said feeder-frame, a multiple-crank shaft journaled inthe outer ends of said side arms, a series of alternately reciprocatingand vibrating downwardly-inclined notched feeding and spreading barsconnected at their upper ends to said crank-shaft, and a vibratingdelivering-pan connected at its lower edge in frontl of the cylinder toone or more of said bars and working thereunder, substantially as setforth.

2. In a band-cutter and feeder, the combination, with athrashing-machine having eX- tended side arms, of an endless-carrierfeederframe hinged to the outer ends of said feederarms, aknife-cylinder journaled upon said feeder-frame, a fender-plate in frontof said knife-cylinder, a multiple-crank shaft journaled in the outerends of said side arms, a series of alternately-reciprocating notchedfeeding and spreading bars connected at their upper ends to saidcrank-shaft, a vibrating delivering-pan connected at its lower edge toone or more of said bars and working thereunder, and a hinged float-board hinged to said fender-plate and normally lying directly over saidfeeding and spreading bars, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.

DAVID GWIN.
